Ceramic Slurry Pump Impellers are made of Silicon nitride bonded silicon carbide material,It is mainly used for Wear and Erosion resistant working applications. Tobee® manufactures high quality slurry pump ceramic impellers and liners replacement parts for some all AH slurry pumps, which are 100% INTERCHANGEABLE.
Tobee® ceramic slurry pump impellers with silicon nitride bonded silicon carbide (Si3N4-SiC). There are many good characteristics of slurry pump ceramic impellers, such as abrasion resistance, corrosion resistance etc. Now the parts are continually provided for coal power generation, non-ferrous foundry, mining and others.
The corrosion and abrasion resistance of ceramic slurry pump parts are highly exceed ones made by high chrome alloy. The abrasion resistance of Si3N4-SiC material is 3.5 times as wearable as Cr15Mo3 (A07). However the weight of Si3N4-SiC material is only 1/3 of high chrome alloy slurry pump parts.
Wear Rate Under the Same Condition
| No. | Materials | Abrasion Rate | Rate Note 1 |
| 1 | composite material | 0.02 | 1 |
| 2 | Sintered ceramic | 0.021 | 1.43 |
| 3 | Casting ceramic | 0.03 | 1.9 |
| 4 | A49 hyperchrome alloy | 0.1 | 4.76 |
| 5 | Duplex Stainless Steel | 0.282 | 13.4 |
| 6 | Teflon | 0.389 | 18.5 |
| 7 | Natural Rubber | 0.5 | 23.8 |
| 8 | SiC Painting | 1.229 | 58.5 |
| 9 | SUS304 | 1.463 | 69.7 |
Note 1: Rate based on SiC-Si 3 N 4, Value=1.
Tobee® ceramic slurry pump impellers show greater anti-abrasion performance than the other materials in impellers.
Contrast of Anti-Corrosive Performance
In regards of wear resistance, metals are only a compromise between conflicting requirements. Having only corrosion and no abrasion, it will be also possible to use Hastelloy. It’s the same with abrasion only. Abrasion in a neutral medium can be done by using Ni-hard or similar. Tobee‘s ceramic slurry pump impellers casting advanced ceramics covers both corrosion and abrasion perfectly. It could be a quite advantageous if there were solids in combination with non-neutral slurries, a leach or an acid (PH-value 0-12).
